COFFEE-URN.

SPECIFICATION forming part of Letters Patent No. 481,851, dated August30, 1892. Application led February 16, 1892. Serial No. 421,744. (N omodel.)

To aZZ whom it may concern:

Be it known that I, FREDERICK DOERING, of the city of St. Louis, in theState of Missouri,have invented a certain new and useful Improvement inCoffee-Urns, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

This improvement relates to the manner of supportinganearthenware,stoneware,or glass coffee crock or yessel in the metal casecontaining the hot Water.

The invention consists in incasing the rim of the coee-vessel with a tincollar having an out-turned marginal ange resting upon the top of theinclosing vessel. The crock is liable to be cracked or broken, and thenthe Whole urn must be thrown away or the crock removed from the metalcase and a new crock substituted.

It is believed that it has heretofore been the constant practice wherecrooks are used to cement them fastin the metal cases. When this isdone, the crock can only be removed with great difficulty and the caseis usually destroyed in the operation. "With my improved constructionthe crock may be simply lifted from the metal case after thedischargepipe has been disconnected.

Figure I is an axialsection of the urn. Fig. II is a horizontal sectiontaken at the jagged line II II, Fig. I. Fig. III is atop view of the urnwith the lid and crock-cover removed. Fig. IV is an enlarged detailvertical section taken at line IV IV, Fig. III.

The metal case 1 may be of cylindrical or other form. It is adapted tocontain water that may be heated by any usual means.

The supporting-legs are shown at 2.

3 is a funnel fixed to the side of the case, through which water may bepoured in. t

Il is the lid of the funnel.

5 is a cock for the discharge of water from the metal case or vessel 1.

6 is the crock or coffee-vessel, having a anged or beaded rim 7,embraced by thelips 8 8b of the metal collar 8.

8a is the upper lip, and 8b is the lower lip. The lip 8f has a fiange 81fitting over the coffee-vessel, and the lip Sbhas aflange 8e tting underthe coffee-vessel. This collar has a flange 8C, that extends over theupper edge 1"L of the vessel 1 and makes a practically tight jointtherewith, so as to check the escape of steam. The side of the collarmay fit tightly in the top of the vessel 1.

9 is a cover fitting alike the upper parts of the collar 8 aud vessel 1.

10 is the cover of the crock.

11 is a discharge-pipe fitted with a tight joint 12 in the crock, andalso with a tight joint 13 in the side of the vessel 1, the pipeextending from the inside of the crock to the outside of the vessel 1and havingadischargecock 14. The pipe 11 is shown passing through thebottom of the crock. It may pass through any part.

I claim herein as new and of my invention- 1. The combination, with thecoffee-vessel and inclosing vessel, of the metal collar 8, secured tothe upper rim of the coffee-vessel and fitting the upper rim of theinclosing vessel, substantially as set forth.

2. The combination, with the inclosing vessel and the coffee-vesselhaving a flange 7, of the collar 8, provided with a ange 8, by which itis supported, with a lower lip 8b, having a flange 8e, and with theupper lip 8, having a iiange 8d, substantially as described.
